Drinking tea is linked to a dramatic reduction in the risk of cognitive impairment in older people, new research suggests.
A single daily cup of tea reduces cognitive decline in those over 55 by 50%, the Chinese study found.
Among those with a genetic susceptibility to Alzheimer's, though, this risk reduction increased to 86%.
It did not matter which type of tea people consumed: green, black or oolong.
The only thing that mattered was that the tea was brewed from tea leaves.
A tiny moon of Saturn has most of the conditions necessary for life, Nasa announced on Thursday, unveiling a discovery from an underground ocean that makes the world a leading candidate for organisms as humans know them.
Scientists stressed that the discovery on a moon named Enceladus is not evidence that life has in fact developed on another world, but they have managed to establish the existence of the water, chemistry and energy sources that are necessary for it.
"We now know that Enceladus has almost all of the ingredients that you need to support life as we know it on Earth," said Linda Spilker, a project scientist who said the finding essentially confirmed vents on the moon's seafloor...
Employee burnout is a common phenomenon, but it is one that companies tend to treat as a talent management or personal issue rather than a broader organizational challenge. That's a mistake.The psychological and physical problems of burned-out employees, which cost an estimated $125 billion to $190 billion a year in healthcare spending in the U.S., are just the most obvious impacts. The true cost to business can be far greater, thanks to low productivity across organizations, high turnover, and the loss of the most capable talent. Executives need to own up to their role in creating the workplace stress that leads to burnout—heavy workloads, job insecurity, and frustrating work routines that include too many meetings and far too little time for creative work. Once executives confront the problem at an organizational level, they can use organizational measures to address it.
In our book Time, Talent and Energy, we note that when employees aren't as productive as they could be, it's usually the organization, not its employees, that is to blame. The same is true for employee burnout. When we looked inside companies with high burnout rates, we saw three common culprits: excessive collaboration, weak time management disciplines, and a tendency to overload the most capable with too much work. These forces not only rob employees of time to concentrate on completing complex tasks or for idea generation, they also crunch the downtime that is necessary for restoration. Here's how leaders can address them.
Many leaders are now aware of the dangers of collaboration overload and collaboration-tool overload in the workplace. The evidence continues to mount that, for many organizations, the costs associated with meetings, emails, IMs and other forms of workforce collaboration now exceed the benefits.
But what can get lost in the eye-popping statistics around excess email and meetings is this: Collaboration overload is almost always a symptom of some deeper organizational pathology and rarely an ailment that can be treated effectively on its own. Attempts to liberate unproductive time by employing new tools (for example, Microsoft Teams, Slack, Box) or imposing new guidelines and meeting disciplines will prove fruitless unless steps are taken to deal with the underlying organizational illness. Companies that have successfully combatted the excesses of overload have done so by focusing on the root causes of unproductive collaboration—and not merely the symptoms—in devising the cure.
Sweden has become the first Western nation to develop national dietary guidelines that reject the popular low-fat diet dogma in favor of low-carb high-fat nutrition advice.
The switch in dietary advice followed the publication of a two-year study by the independent Swedish Council on Health Technology Assessment. The committee reviewed 16,000 studies published through May 31, 2013.
Swedish doctor, Andreas Eenfeldt, who runs the most popular health blog in Scandinavia (DietDoctor.com) published some of the highlights of this study in English:
Health markers will improve on a low-carbohydrate diet:
…a greater increase in HDL cholesterol ("the good cholesterol") without having any adverse affects on LDL cholesterol ("the bad cholesterol"). This applies to both the moderate low-carbohydrate intake of less than 40 percent of the total energy intake, as well as to the stricter low-carbohydrate diet, where carbohydrate intake is less than 20 percent of the total energy intake. In addition, the stricter low-carbohydrate diet will lead to improved glucose levels for individuals with obesity and diabetes, and to marginally decreased levels of triglycerides." (Source.)
For more than half a century, the conventional wisdom among nutritionists and public health officials was that fat is dietary enemy number one – the leading cause of obesity and heart disease.
It appears the wisdom was off. And not just off. Almost entirely backward.
According to a new study from the National Institutes of Health, a diet that reduces carbohydrates in favor of fat – including the saturated fat in meat and butter – improves nearly every health measurement, from reducing our waistlines to keeping our arteries clear, more than the low-fat diets that have been recommended for generations. "The medical establishment got it wrong," says cardiologist Dennis Goodman, director of Integrative Medicine at New York Medical Associates. "The belief system didn't pan out."
Delusions come in all shapes and sizes; from transient episodes to full-blown and incurable mental illnesses.
But they all have one thing in common: being detached from reality. Delusions do not listen to reason and they do not bow to facts.
Most of the CEOs I've met and worked with had years to prepare for their jobs. As they entered middle management, most of them learned that being a good leader is more important than being a good do-er. Many have stories to tell about stumbling along the way, about micromanaging people, about destroying a team's morale with unreasonable demands, about losing a great team member because enough time and attention weren't given to the relationship.
Most survived these types of difficult experiences and, more important, learned from them. They learned to let go of control and instead support people in doing their jobs. They learned to watch their teams for signs of burnout and rebellion. They learned to help people work smarter, not harder. They learned to read people well. They got very good at recognizing who needs appreciation, who needs support, who's motivated by achievement, and who needs very collegial relationships — even with the boss. They learned tricks for building stronger teams, for dealing with conflict, and for negotiating.
Male depression is a serious medical condition, but many men try to ignore it or refuse treatment. Learn the signs and symptoms — and what to do.
Do you feel irritable, isolated or withdrawn? Do you find yourself working all the time? Drinking too much? These unhealthy coping strategies may be clues that you have male depression.
Depression can affect men and women differently. When depression occurs in men, it may be masked by unhealthy coping behavior. For a number of reasons, male depression often goes undiagnosed and can have devastating consequences when it goes untreated. But male depression usually gets better with treatment.
Male depression signs and symptoms
Depression signs and symptoms can differ in men and women. Men also tend to use different coping skills — both healthy and unhealthy — than women do. It isn't clear why men and women may experience depression differently. It likely involves a number of factors, including brain chemistry, hormones and life experiences.
Emotionally intelligent people are the advice-givers among their group of friends. Do you have a friend who seems to know what you're feeling before you've verbalized it? This friend is emotionally intelligent. There are many of those people in the world. They are the healers, the untrained therapists among friends.
"Oh, ask Stacy. She always knows what to do." Stacy is emotionally intelligent. That's why she knows what your boyfriend is thinking having never had more than a five-minute conversation with the dude.
You've always been a high achiever—top of your class, captain of your sports teams, star performer at work. Now, you're going to be managing a team of high-performers in a division of your company that everyone's buzzing about. You're confident that you can navigate this new challenge with characteristic success.
You're pumped. You set clear goals for yourself and targets for the division. You're well aware that you'll need to rely on your emotional intelligence skills to understand and work through your new team's dynamics. You're focused on achieving your goals and getting results… but before long, you've got problems. Your team doesn't seem to be on board with your plan and they're not delivering. Worse, they seem to be shutting you out. In desperation, you go to a few trusted mentors who tell you:
"You've inherited the cream of the crop. I'm not sure they even really need a manager, they're that good and that motivated."
"These are our stars. You noticed, I'm sure, that you're the third new manager appointed in the past two years?"
A 'gene signature' that could be used to predict the onset of diseases, such as Alzheimer's, years in advance has been developed in research published in the open access journal Genome Biology.
The study aimed to define a set of genes associated with 'healthy ageing' in 65 year olds. Such a molecular profile could be useful for distinguishing people at earlier risk of age-related diseases. This could improve upon the use of chronological age and complement traditional indicators of disease, such as blood pressure.
Lead author James Timmons, from King's College London, UK, said: "We use birth year, or chronological age, to judge everything from insurance premiums to whether you get a medical procedure or not. Most people accept that all 60 year olds are not the same, but there has been no reliable test for underlying 'biological age'.
A new study by Duke University researchers suggests that this type of scenario makes a person less likely to remember what halted the action — for example, the make and model of the car in the blind spot.
People and non-human primates excel at "response inhibition." Our sophisticated brains allow us to cancel an action even when it's something engrained, like driving on the right side of the road. Although it's not easy, we can override this inclination when we drive in foreign countries with left-hand traffic.
The new results, published Aug. 26 in the Journal of Neuroscience, lend insight into how the ability to inhibit an action — a fundamental aspect of everyday life — affects other important brain functions such as attention and memory. The findings may eventually inform the treatment of disorders characterized by difficulty inhibiting actions, such as attention deficit hyperactivity disorder (ADHD) and addiction.
Dogs have a specialized region in their brains for processing faces, a new study finds. PeerJ is publishing the research, which provides the first evidence for a face-selective region in the temporal cortex of dogs.
"Our findings show that dogs have an innate way to process faces in their brains, a quality that has previously only been well-documented in humans and other primates," says Gregory Berns, a neuroscientist at Emory University and the senior author of the study.
Having neural machinery dedicated to face processing suggests that this ability is hard-wired through cognitive evolution, Berns says, and may help explain dogs' extreme sensitivity to human social cues.
